Description

The invention relates to a method for reducing the wear of an endlessly circulating belt, in particular a fabric in a machine for producing fibrous webs having a surface which is guided over a part of their circulation path with a further surface to form a contact area, wherein both surfaces free from contact with a fibrous web.

The invention further relates to a device for treating a material web, in particular fibrous web in the form of a paper, board or tissue web, with an endlessly circulating belt, in particular stringing, with a surface which contacts a further movable surface over a portion of its circulation path and under Training a contact area is performed, wherein the contacting surfaces are free of contact with the fibrous web

Devices for the treatment of webs of material are known in different embodiments from the prior art. These are, for example, in the form of drying devices to facilities in a machine for producing such webs, which serve to increase the dry content of a web following a press device or so-called after-treatment devices in the form of calendering, which produce certain surface properties of the treated Material web, especially smoothness can be used. In machines for the production of fibrous webs and / or aftertreatment devices thereby systems are used, in which the fibrous web together with one or more endlessly circulating Ribbons is passed through a treatment line. In this case, the individual endlessly circulating belts are usually driven separately and are arranged inside one another and form a contact region between them, as a result of which relative movements between the contacting bands may possibly occur. These require increased wear on the contact surfaces forming sides of the respective endless circulating belts, which can lead to a reduction in the availability of this and the entire device. In drying facilities such as in the WO 2005/100682 A1 described metal bands use, which are performed together with a drying wire between a pressure hood and a drying cylinder under the leadership of the dryer fabric supporting fibrous web. The embodiment described therein is characterized by a sealing arrangement for sealing a first, containing a pressurized medium component in the form of the pressure hood by a sealing element against a relative to the first component moving second component in the form of an endless circulating belt. When the seal assembly is touching seals in the form of abrasive seals, in which the sealing surface of the sealing element is applied directly to the moving component, whereby a sliding pair between the two bodies is present with solid friction. When grinding seals cause the friction forces occurring in addition to increased wear of the elements involved in the friction pair resistance to the movement of the moving component, so that a higher drive power is required. The resulting significant heat development of the seals or the dense band favors wear, which can occur through local overheating and destruction. To avoid these disadvantages, therefore, a small amount of leakage of the pressurized medium is allowed, which adjusts depending on the pressure in the pressure hood. The seal assembly is characterized by a further second seal which is downstream of the first seal in the direction in which pressurized medium may escape or escape from the first component. If the first seal has a certain leakage, medium escaping through it can, especially if it is is a liquid, the surface on which the second seal slides on the surface of the second component, lubricate and thereby reduce the friction. The lubricating effect is dependent on the amount of escaping through the first seal medium and thus of the operating parameters of the entire system. In this case, the lubricating effect on the second sealing element of the sealing arrangement is always dependent on the leakage through the first sealing element. However, this can be different, in particular due to uneven wear on the first sealing element, over the length and width of the first sealing element, so that on the second downstream sealing element along its length also different lubricating effects can be achieved. This leads in the worst case to different friction conditions over the extension of the sealing element, in particular over the machine width and favors uneven wear of the sealing element, which can lead to shortened maintenance intervals for the sealing element. Furthermore, a poorer sealing effect of the sealing arrangement may impair the function of the drying device.

Other configurations of clothing that interact with a movable surface and are subject to increased wear due to relative movements are, for example, from the document WO 2006/024695 A1 previously known. The device described therein is a calendering device comprising two calender rolls which form at least one nip with each other, wherein the fibrous web is passed through the nip with a string. Again, there is a risk of increased wear due to relative movements to each other between the contacting surfaces, in particular a calender and the inside of the fabric. The document further discloses a device for cleaning the metal strip by applying a cleaning agent to the process surface following the calendering nip.

The invention is therefore based on the object, a method for reducing the wear of endless circulating belts in a machine for manufacturing of fibrous webs such that the disadvantages mentioned are avoided and the availability of such bands, in particular when in contact with other movable surfaces, wherein between two operating states with occurring relative movement are possible, can be increased.
